Custom built arms of any length must clamp to the
swing/pull clamp’s piston rod in a manner similar to the
DE-STA-CO arms or some derating of the clamp will
be necessary.

The design feature “K”, in the chart and drawing at the
bottom of this page, is recommended for all applications of
custom, single arms. See the accompanying chart for design
details. In applications where there is no bending stress
being transferred into the piston rod (like push/pull linkages
and equalizing double arms), this design detail may be
eliminated. In these applications, the clamp’s full capacity
(referred to as “straight pull” capacity) is available

IMPORTANT: Any clamp using a modified or custom arm that is longer or heavier than DESTACO’s standard arms must be derated to prevent internal damage.

* Do not exceed the maximum speed and pressure ratings for DESTACO’s standard arms. For maximum hydraulic pressure and speed ratings, see the accompanying charts.

* Do not use meterout circuitry for controlling doubleacting clamp speeds.

* Contact DESTACO if further design assistance is required.
